Ice Making Sequence of Operation
CNF201 - CNF202 NUGGET MACHINES
Ice Making Sequence of Operation
PRIOR TO START-UP
When the toggle switch is placed in the ICE position, the
following must occur in the listed order before ice making
will start.
• The 15-minute delay period must be expired. The
delay period starts upon application of power or a
change in toggle switch position.
• The ice chute damper must be in the closed or down
position.
• The water sensing switch must be closed (water
reservoir full of water and water sensing float in the up
position).
INITIAL START-UP
A 15-minute delay period must expire. The delay period
starts to time out upon application of power and can
only be overridden by depressing the test switch on the
control board. The gear motor energizes and when water
in the reservoir closes the water sensing (float switch) the
compressor and condenser fan motor energize.
FREEZE CYCLE
The float valve automatically maintains the water level in
the reservoir. The ice damper will open and close to verify
ice production. The ice machine will continue to make ice
until the ice damper is held open (up) as ice fills the bin.
Operation
22 Part Number 000015432 4/18
AUTOMATIC SHUTOFF
When the ice damper is held open by ice, the gear motor,
compressor and condenser fan de-energize. The ice
machine will remain off until the 15-minute delay period
expires and the ice damper closes.
RESTART AFTER AUTOMATIC SHUTOFF
The 15-minute delay period must be expired. The delay
period starts when the ice machine enters Automatic
Shutoff and can not be overridden.
The restart sequence is dependent on the amount of time
the ice machine has been off:
1. The ice machine was off for less than 30 minutes.
When the 15-minute delay period expires, the gear motor,
compressor and condenser fan motor energize.
2. The ice machine was off for more than 30 minutes.
The gear motor and dump valve energize to drain the
water from the evaporator and reservoir. After 45 seconds,
the dump valve de-energizes. When the reservoir fills with
water, the water sensing switch closes and the compressor
and condenser fan motor energize.
CHANGING TOGGLE SWITCH POSITION IN THE
FREEZE CYCLE
Moving the toggle switch from ICE to OFF will start a
15-minute delay period.
• Moving the toggle switch immediately to the ICE
position - The ice machine waits 15 minutes, then
starts.
• Moving the toggle switch to the ICE position after 15
minutes have elapsed - The ice machine immediately
starts.
Part Number 000015432 4/18 23
Control Board Features
POWER INTERRUPTION DELAY
If power is disconnected, the ice machine stops. When
power is reapplied, a 15-minute delay is initiated.
SAFEGUARDS
The ice machine control board has safety features to
protect the ice machine from severe failures. The ice
machine will stop when conditions arise that would cause
major component failure. Refer to Safeguards for details.
TOUCH PAD SEQUENCE OF OPERATION
1. The control board monitors the touch pad. Pressing/
selecting Ice, Water, or Ice & Water will energize
the corresponding blue Led selection and waits for
dispense lever or touchless sensor activation.
2. Depressing the dispense lever or activating the
touchless sensor closes the relay selected with the
touch pad. Depending on selection, either the water
solenoid, ice dispense motor or both components
activate.
WATER LEVEL CHECK
The float valve maintains the correct water level. The
water level is factory set and normally will not require
adjustment. The water level is correct if the Water Level
indicator light is energized and no water is entering the
overflow tube.
The float valve is secured with 2 stop nuts. If an
adjustment is required, raise or lower the stop nuts as
needed.

Maintenance
26 Part Number 000015432 4/18
Manitowoc’s Cleaning Technology
Manitowoc CNF201 - CNF202 Ice Machines allow the
initiation and completion of a cleaning cycle at the flip
of a switch. This cycle will permit cleaning of all surfaces
that come in contact with the water distribution system.
Periodic maintenance must be performed that includes
sanitizing the bin and adjacent surface areas, which are not
contacted by the water distribution system.
Depending on local water conditions Manitowoc
recommends initiating preventative maintenance
cleaning procedures between the 6-month cleanings. This
preventive maintenance removes mineral build-up from
the evaporator, which results in peak efficiency and lower
operating costs.
This technology allows initiation and completion of a clean
cycle, after which the ice machine automatically starts ice
making again.
There are three separate cleaning procedures.
Heavily Scaled Cleaning Procedure
Perform this procedure if you have some or all of these
symptoms.
• Grinding, popping or squealing noises from the
evaporator.
• Grinding noise from gearbox.
• Ice machine trips speed sensor.
A Cleaning/Sanitizing Procedure must be performed after
this procedure.
Cleaning/Sanitizing Procedure
This procedure must be performed a minimum of once
every six months:
• All ice must be removed from the bin/dispenser.
• The ice machine and bin/dispenser must be
disassembled, cleaned and sanitized.
• The ice machine produces ice with the cleaner and
sanitizer solutions.
• All ice produced during the cleaning and sanitizing
procedure must be discarded.
Part Number 000015432 4/18 27
Preventative Maintenance Cleaning Procedure
Perform this procedure as often as required for your water
conditions:
• Allows cleaning the ice machine without removing all
of the ice from the bin/dispenser.
• Removes mineral deposits from areas that are in direct
contact with water during the Freeze cycle (reservoir,
evaporator, auger, drain lines).
EXTERIOR CLEANING
Clean the area around the ice machine as often as
necessary to maintain cleanliness and efficient operation.
Use cleaners designed for use with stainless steel products.
Sponge any dust and dirt off the outside of the ice machine
with mild soap and water. Wipe dry with a clean, soft
cloth.
Heavy stains should be removed with stainless steel wool.
Never use plain steel wool or abrasive pads. They will
scratch the panels.
WEEKLY
Remove grill from scrap ice tray and wipe splash panel,
scrap ice tray and grill with sanitizer & water solution. Pour
excess solution in scrap ice tray to clear drain.
TOUCHLESS SENSOR ONLY
Wipe sensor window with a soft cloth and mild detergent.
Rinse with clear water and dry with a clean soft cloth.
Dust and dirt can be removed from exterior surfaces with
mild household dish-washing detergent and warm water.
Wipe dry with a clean, soft cloth.
28 Part Number 000015432 4/18
Preventative Maintenance Procedure
